COMBINATION-Tool..

SIPECIFICATION forming part of Letters Patent No. 506,416, dated October 10, 1893.

Application led December Z4, 1892. Serial No. 456.234. `(No model.)

To all whom it may concern.'

Be it known that I, SIMEON COLLEY, a subject of the Queen of Great Britain, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Combination-Tools, of which the following is a specification.

My invention relates to improvements in combination tools, and it especially relates to a tool designed for machinists, mechanical engineers and mechanics generally.

The object of my invention is to provide a single tool adapted to' performsuccessfully the functions of various tools which have heretofore been generally constructed separately.

My invention consists in the various constructions and combinations of partshereinafter described and pointed out in theclaims.

In the accompanying drawings Figure l is a plan view of my improved tool. Fig. 2 is a similar view from the opposite side, showing the parts in a different position of adjustment. Fig. 3 is a side elevation of the tool, as illust-rated in Fig. 2. Fig. 4 is a transverse sectional view on the line XXin Fig. 1.

Like parts are represented by similar letters of reference in the several views.

The tool consists essentially of a head a, of a peculiar construction, (the exact description of which will more fully appear hereinafter) and a blade or rule b. The head a, is provided on one side with a groove or depression a', formed exactly at right angles to one of the faces a2, of said head which we will term the base. This depression a', is adapted to receive the blade or rule b, which ts snugly therein; the groove or depression being of a depth equal to about half the thickness of the rule or blade, the blade being thus held in its normal position in said groove and at exactly right angles to the base d2, of the head a. The head a, is further provided near the center, and in line with the depression or groove a,with a swivel piece o, which fits in a depression a3, in the head, of a depth greater than the depth of the groove a. This swivel piece c, is also provided with a groove c', correspondinglfin size and depth to the groove a', in the head a, and adapted, in the normal position, to stand in line with said groove-or depression.,

The swivel piece c, is further provided with a spring c2, preferably formed to fit over and cover the end of the swivel piece as well as the groove c', therein, said spring being provided with projecting ends in line with the said groove c', and adapted to bear on the rule or blade b, when inserted into said groove c; this spring c2, being thus adapted to exert a yielding pressure against the blade b, forming the tension therefor, which will hold the same yieldingly in any position of adjustment and yet permit it to be moved readily to change the adjustment thereof. The swivel piece c, is further provided with a screw-threaded stud o3, vwhich projects through the head d, and is provided with a thumb-nut c4, and asuitable washer c5, on the opposite side of said head, by means of which the swivel piece may be drawn firmly into the depression d3, thus clamping the blade b, firmly against said head in any uposition which it may occupy, as hereinafter more fully described.

The head o, is provided on opposite sides with beveled faces d4, o5, formed at an angle offorty-five degrees and the other at an an- ,gle of thirty degrees to the base a2, the said faces being thus at an angle of -forty-five degrecs and sixty degrees, respectively, to the The face a4, is further provided gles to the face a4, and at an angle of fortyfive degrees to the base a2, and the blade b,

l when in its normal position. The outer end of this projection a6, is provided with a face a7, which is exactly in linewith the end d8, of the base a2, and in a plane parallel to the groove a', of said head, as indicated by the dotted line Z Z-in Fig. l. At the opposite end of the head a, is a V-shaped notch a9, the sides of which occupy the same angular positions with relation to each other as the sides of a screw-thread; this end ofthe head being also formed on a right line parallel to the groove d', and thus at right angles to the base a2, as

indicated by the dotted line Y Y in Fig.' 1.

That side of the head o., which contains the groove a', is graduated, so that when the blade b, is removed from-the groove a', and turned so as to rest on the face of the head o, the

graduations will indicate the different degrees in the arc of a circle, extending from the center of the swivel piece c; the device being thus adapted to operate as a beveled square or protractor. The juncture of the projection a6, with the face at, is in such relation with the swivel piece c, that when the blade b, is turned exactly parallel with the base a2, one edge of said blade bisects the angle formed at d10, by the projection a6, and the face d4; a small projection 0.11, being formed on the face of the head at this point to limit the movement of the blade and thus determine the exact locationt-hereof when turned to this position as shown in Fig. 2. The sides of the angle 0.10, together with the blade d, form a center gage by means of which the center of any circular piece may be determined by placing the sides of the angle against the periphery of the said piece with the blade extending over the top thereof, in a well known manner.

It should be stated that the blade b, is preferably graduated into units and fractions thereof, `or any other unit of measurement. Vhen in the normal position, the blade being exactly at right angles to the base a2, which is adapted to be used as a T-square or a trisquare, the projecting end of the blade, together with the base a2, is adapted to be used as a depth gage, to measure the depth of holes or openings. One end of the rule h, is preferably rounded,as shown at b', for this purpose; the rulebein g reversed from end to end to bring therounded portion opposite the base a2, when desired; this being accomplished by swinging said rule about the head in the swivel piece c. To provide a depth gage for smaller openings than those adapted to receive the blade b, I provide a small rod e, which normally lies in a groove in the washer c5, which maintains said pin parallel with the groove a,`and at right angles to the base a2; a small spring `e', being preferably provided to bear against said rod,

to furnish the proper-tension therefor; the4 washer c5, being adapted to clamp said rod and lhold it iirmly against displacement when the thumb-nut c4, is tightened. Y

The V-shaped notch a9, it will be seen, forms a gage for a thread tool, both for grinding and setting the same. In setting a thread tool the head a, is placed in position against the lathe rest with the line Z Z determined by the faces a7 a8, as a base line. The tool is turned until it comes in the groove a9, which brings it to the proper position. The beveled sides a4, d5, of forty-five and `sixty degrees, furnish the means of laying off hexagon and Octagon figures and take the place of the ordinary angles usually employed by draftsmen and mechanical engineers. By using the faces a7, as, as a base line a perpendicular is obtained by the base a2; the head Vci, being thus adapted to be used as a triangle, the blade b, in this case being removed or slipped back beyond the base a2. Then the blade b, is turned upon the head a, out of the groove Ct', it rests directly in contact with the side of said head and can be secured in any position by tightening the thumb-nut c4; at the same time by loosening said thumb-nut it may be adjusted to any position about said head or through the swivel, while the spring.

c2, maintains the proper tension thereon at all times. i

It will be seen that a tool as thus described may be readily adj usted to any work for which it is adapted, and furnishes in a single tool what the mechanic or artisan must usually seek for in various different devices.

Having thus described my invention, I claiml. In a combination tool, a head formed with a base, and `a groove or depression at right angles to said base, a blade adapted to normally tit in said groove or depression, a swivel piece also having a groove to receive said blade, a spring attached to said swivel piece to form a tension for said blade, and a thumb-screw extending through said head, adapted to tighten said blade in said head and in said swivel piece, respectively, substantially as specified.
